So I actually think there's a lot of interesting ideas here.

- Love the idea of a continuous timeline view in the "day" view. Not sure how I feel about the horizontal scrolling. Mostly I dislike the vertical-oriented text, but maybe I'd get used to it.

- Love the daily habit tracking built right in.

- Love the "some time this week" feature.

- I like the "maybe" calendar.

I dropped my @hey email address after a year because I quickly learned that having a built-in Calendar was a non-negotiable must-have for me (it turns out that most of my personal emailing is about coordinating events...ha!) I might fire it back up for a year to give it another go now that they have a more native calendar integration.

The design language is very much 37 Signals/Basecamp/Hey. You'll either love it or hate it.
